ALBERT BLAIR, 0F GENESEO, ILLINOIS.

CHURN.

Application filed October 14, 1911.

T 0 all whom it may concern:

Be it known that I, ALBERT BLAIR, a citizen of the United States,residing at Geneseo, in the county of Henry and State of Illinois, haveinvented certain new and useful Improvements in Churns, of which thefollowing is a specification.

This invention relates to improvements in barrel or box churns.

The primary object of this invention is to provide a device of thischaracter that will churn the cream in about half the time requiredthrough the use of the ordinary barrel or box churn, the condition ofthe milk, temperature, etc., being equal.

WVith the foregoing and other objects in view, the invention consists inthe novel features of construction, combination and arrangement of partsillustrated in the drawings and more particularly pointed out in theappended claims.

In the accompanying drawings :Figure 1 is a side elevation of a churnembodying my improvements. Fig. 2 is a side elevation with the churntilted at an angle of about fifteen degrees with a vertical plane. Fig.3 is a central vertical section of Fig. 2. Fig. 4 is a horizontalsection taken on the plane indicated by the dotted lines 4-4 of Fig. 1.Fig. 5 is a sectional elevation of a modification, and Fig. 6 isvertical section taken on line 6-6 of Fig. 5, looking in the directionindicated by the arrows.

Referring to the drawings for a more particular description of theinvention, the churn body is herein shown in the form of a barrel 1revolubly mounted at the center between standards 2 of the supportingframe 3. A shaft 4 is bolted at lts inner end to one side of the barreland is mounted to turn in the upper end of the adjacent standard, theouter end of said shaft being provided with the crank handle 5. Astationary shaft 6 projects inwardly from the other standard and forms abearing for the disk or plate 7 which is bolted to the opposite side ofthe barrel and turns on shaft 6. A stationary gear 8 is mounted on theshaft 6, the purpose of which will be hereinafter specified.

A double winged paddle 9 is mounted to turn within the churn body as thelatter is rotated. Said paddle is suitably keyed to a shaft 10, one endof which is mounted to turn in a bearing 11 bolted to the inside of thechurn body and the opposite end of Specification of Letters-Patent.

Serial No. 654,576.

which extends through and beyond the opposite side of the churn body. Apinion 12 v is secured to the projecting end of the paddle shaft by thepin 13 and is provided with a peripheral flange 14, which works againstthe inner face of the stationary gear Q, as shown in Figs. 1 and 2. Theflange 14 holds the inner end of the shaft in its socket or bearing 11and thereby prevents any endwise displacement of the shaft or paddleduring the churning operation. A packing ring 15 receives one end of theshaft where it pierces the churn body and prevents any of the contentsof the churn from leaking out. To remove the shaft 10 for any reason, itis first necessary to remove the pin 13 of the gear 12 and the pin 16 ofthe paddle.

It will be understood that as the churn is turned by means of the crankhandle 5, the pinion 12 travels over the fixed gear 8 which causes theformer to rotate and thereby rotate the paddle. The paddle is so gearedthat when the barrel is at an angle of approximately fifteen degrees toa vertical plane, the paddle extends in the same plane as the barrel, soas to offer the least possible obstruction to the removal of thecontents or the cleaning of the churn body.

In the modification illustrated in Figs. 5 and 6, the flange 14 ofpinion 12 is dispensed with and the gear or pinion arranged to travelaround the teeth 17 of the gear 18.

From the foregoing description taken in connection with the drawings, itis thought that the construction and advantages of this invention willbe readily understood without requiring a more extended explanation.

Having described my invention, what I claim as new and desire to secureby Letters Patent, is

1. In a churn, a supporting frame, a churn body in the form of a barrelor box mounted at its center in the frame, a paddle shaft extendingthrough the center of the churn body eccentric to the central transverseaxis thereof, a fixed gear on the frame, a paddle keyed to the shaft,paddle arms carried by the paddle shaft and extending in oppositedirections, paddles at the outer ends of said arms, and a pinion on oneend of the shaft arranged to travel over the fixed gear when the churnbody is rotated, whereby the paddle shaft and paddle are rotated Withinthe churn body, with means for rotating the churn body by hand power,the paddle being so arranged on its shaft that the Wings or bladesthereof are disosed in alinement and extend in a plane ith the churnbody When at an angle of approximately fifteen degrees With a verticalplane.

2. In a churn, a supporting frame, a churn body in the form of a box orbarrel revolubly mounted at its center in the frame, a fixed gear at theupper end of the frame, a paddle shaft arranged eccentric to the centraltransverse axis of the churn body With one end extending through theWall thereof, a bearing on the inner Wall of the churn body for theinner end of the shaft, a paddle keyed to the shaft, a pinion on theprojecting end of the shaft arranged to intermesh With or travel overthe fixed gear as the churn body is rotated and a peripheral flange atthe inner face of the pinion engaging the inner face of the fixed gearwhereby the paddle shaft is held against endwise displacement When thechurn is rotated.

In testimony whereof I affix my signature in presence of two witnesses.
